Abstract
The utility model discloses an automatic plastic bottle blowing machine. The automatic plastic bottle blowing machine comprises a front template, a rear template, a bottom template and a mold closing device, wherein the mold closing device comprises a mold closing cylinder. The automatic plastic bottle blowing machine further comprises a lifting cylinder used for pushing the bottom template, wherein the stretching direction of the piston rod of the lifting piston is perpendicular to that of the piston rod of the mold closing cylinder; the piston rod of the lifting cylinder is fixedly connected with the bottom template; and an air inlet I corresponding to the ascending action and an air inlet II corresponding to the descending action are formed on the lifting cylinder and respectively connected with air supply pipelines capable of supplying air independently. The bottom template and the front template, as well as the bottom template and the rear template, are not connected in a clamping manner, so that a mold opening container can be successfully divorced from the bottom template, and the characteristic of short mold opening time is achieved. Therefore, the automatic plastic bottle blowing machine has the advantage of high production efficiency.
Description
Technical field
The utility model relates to a kind of automatic plastic bottle-blowing machine.
Background technology
In the prior art, blower for plastic bottle generally comprises front template, rear pattern plate and end template.End template is connected by the mode of clamping with front template, rear pattern plate, and two air inlets of the lift cylinder of end template connect same low-pressure gas source.When matched moulds, the end template that descends first then makes front template, rear pattern plate matched moulds by the matched moulds cylinder, and end template blocked and forms complete container template.End template by and front template, rear pattern plate between clamping concern to overcome the effect of bottle blowing gases at high pressure.This structure is so that after bottle blowing finishes, die sinking process more complicated, opening in front template, rear pattern plate after the rising of end template, so so that the bottle of moulding can not break away from from end template smoothly, with end template rising adhesion or beat, thereby greatly affect the normal operation of bottle blowing streamline.
Summary of the invention
The technical problems to be solved in the utility model provide a kind of can make the bottle that is shaped can be when die sinking smoothly with the automatic plastic bottle-blowing machine of end template disengaging.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: this automatic plastic bottle-blowing machine comprises front template at least, rear pattern plate, end template, and for starting front template, rear pattern plate, end template also makes the mold closing mechanism that they link together, comprise the matched moulds cylinder that is used to front template and rear pattern plate matched moulds to use on the described mold closing mechanism, described automatic plastic bottle-blowing machine also comprises for the lift cylinder that promotes end template, the flexible perpendicular direction of piston rod of the flexible direction of the piston rod of described lift cylinder and matched moulds cylinder, the piston rod of described lift cylinder is fixedly connected with end template, described lift cylinder is provided with the air inlet I of corresponding vertical motion and the air inlet II of corresponding down maneuver, but described air inlet I and air inlet II connect separately the supply air line of independent gas supply.
The utility model adopts technique scheme: the connected mode of avoiding clamping between end template and front template, the rear pattern plate, so that the die sinking forming containers can break away from from end template smoothly, reached short characteristics of die sinking time, so this automatic plastic bottle-blowing machine has the high advantage of production efficiency.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described in detail.
Fig. 1 is the structural representation of a kind of automatic plastic bottle-blowing machine of the utility model.
The specific embodiment
As shown in Figure 1, automatic plastic bottle-blowing machine comprises frame; And rack-mounted front template 1, rear pattern plate 2, end template 3, bottle mechanism 4, be used for starting front template 1, rear pattern plate 2, end template 3 and make the mold closing mechanism that they link together, be used for promoting the lift cylinder 5 of rear pattern plate 2.
During work, former bottle is placed on the bottle mechanism 4, the former bottle after the placement is near front template 1 position.Then, the air inlet I 8 of lift cylinder 5 passes into compressed air, lift cylinder 5 actions, and piston rod stretches out, and end template 3 produces closely annexation to the motion of front template 1 position until end template 3 contacts with front template 1.Then matched moulds cylinder 6 motions, piston rod stretches out, and rear pattern plate 2 produces closely annexation to the motion of front template 1 position until rear pattern plate 2 contacts with end template 3.At this moment, front template 1, rear pattern plate 2, end template 3 have formed the complete die cavity that is used for the bottle moulding jointly.At last, bottle mechanism 4 blows such as gases at high pressure in former bottle, so that former bottle expands at the die cavity internal shaping, finishes thus the bottle blowing operation.Matched moulds cylinder 6 is died during the demoulding, and rear pattern plate 2 is to the direction motion away from front template 1 position; Lift cylinder 5 only has air inlet II 9 to pass into compressed air, and the piston rod of lift cylinder 5 shrinks, and end template 3 breaks away from front template 1.
The lift cylinder 5 that matching bottom mould plate 3 uses connects the different source of the gas of two-way, the air inlet of the corresponding down maneuver of lift cylinder 5 can connect high-pressure air source with the active force of opposing bottle blowing gases at high pressure, and the air inlet of the corresponding vertical motion of lift cylinder 5 can connect low-pressure gas source.Thus, avoid the connected mode of clamping between end template 3 and front template 1, the rear pattern plate 2, after opening, end template 3 do not lag behind the opening time of front template 1, rear pattern plate 2,2 pairs of forming containers of front template 1 and rear pattern plate have of short duration rising barrier effect, so forming containers breaks away from from end template 3 smoothly when die sinking.This operating process has short characteristics of die sinking time, so this automatic plastic bottle-blowing machine has the high advantage of production efficiency.
